IMPORTANT NOTICE REGARDING TIMELINE ALTERATIONS
As mentioned in my screaming earlier, I have altered the timeline of “the prank” and the reasons for it have been covered multiple times on my Severus Snape blog. The most in depth of which can be found here; however, I will be copying over the relevant portion and modifying it with Sirius’ POV of matters and why I am keeping this change consistent across the blogs.
“Sirius Black showed he was capable of murder at the age of sixteen,” he breathed. “You haven’t forgotten that, Headmaster? You haven’t forgotten that he once tried to kill me?”
-Prisoner of Azkaban
At sixteen years old Severus is dead right in the fact Sirius is capable of murder. It’s not a joke at sixteen – in fact at sixteen Sirius could reasonably have been tried as an adult in a crime that lead to a death or the passing of a disease in the event Severus was turned. It is even reasonable to believe Remus would have been culled for his participation – for being a dangerous wizard killer.
At sixteen this is so sinister it changes everything about Sirius into something much darker – and while some people might like that, or choose to ignore it entirely, or opt to brush it off as a light hearted joke Remus got over in a few weeks – I genuinely cannot accept that Remus would want to live with a man who did this to him, that Sirius is cast as a good guy, and that this whole thing was buried by Hogwarts staff as the “silly actions of sixteen year olds” when these are the same people who snap wands on sheer fucking hearsay when dangerous animals and murder happen to be involved.
At thirteen it’s easier to see this as meant harmlessly enough for the adults involved to pull the bullshit they did. It is even possible at thirteen to see Sirius as genuinely wanting nothing more than to scare Severus or at the very least chase him off for good. It’s less likely to be a weaponization of Remus, or a deliberate attempt on Severus’ life because frankly at thirteen it’s easier to see the immediate good result than the long term bad ones. Thirteen we’re angry enough to think of horrible things happening to people but we’re not entirely as responsible when we go forth and do them; thirteen year olds are horrible little shits and that’s a fact, but they are rarely cold hearted murderers.
At sixteen, you certainly can be.
Sirius, at thirteen, was still coming to terms with what being friends with a werewolf evenmeant. He had not yet, at this point, spent years beside Remus trying to find a way to make his life better. He was not yet an illegal animagus, he was not yet immersed in how shit this disease really is. He understood werewolves from a pureblood perspective, which is very bigoted, and his perceptions are rather fucked up.
Remus is his friend, and its cool to be a friend with someone who turns into a monster every month – mom would have a fit if she knew, its a fun little secret, it feeds into his rebellious nature – but it’s not pulling his heartstrings. He isn’t sympathetic or understanding – he hasn’t gotten there yet. At sixteen, he has.
At sixteen Sirius has seen this transformation many times. He understands, intimately, how godawful this disease is. He understands how deeply his friend suffers, how much pain is involved in this, how violent and unforgiving the wolf is. How far from Remus that creature can at times be. He knows, viscerally, how scared Remus is of being seen as a monster.
In other words, by that point in time, he grew up. By that point, he had dedicated himself to becoming an animagus and spent many nights out with a werewolf doing all he could to make the experience positive for his suffering friend. There is no fucking way that sixteen year old Sirius would risk exposing Remus. They are truly, deeply friends by that point and bonded not only in their secret but in blood and crime.
Protecting Remus is part of who Sirius is now, so it doesn’t fit for him to do this after spending years alongside him, seeing his pain and suffering, learning to become an animagus, and running alongside him. It just doesn’t fit, especially not if Sirius is supposed to be a good person, but that’s another argument.
The timeline is changed because Sirius changes with time, as people tend to do. At thirteen, he is ignorant of all the implications of sending Snape into the shack. At sixteen, he is not. nd for that reason, I go for thirteen, because sixteen just doesn’t make sense.
That said, I also do not write Sirius as ever apologizing for this, because it will literally take him years to understand how bad it is and we have no canonical evidence of this being anything other than a “prank” so unless a Remus talks to me, an apology is a divergent element. That said? Sirius doesn’t think he deserves forgiveness for what he did. He acknowledges it was stupid.
But he’s also man enough to admit he doesn’t deserve to be forgiven, just because he was young and dumb, when its literal lives he could have destroyed that night.
